DUPLEX OPERATION

Duplex operation allows the radio to transmit on a different frequency to that which

it receives. This allows operation through repeater stations in your area. Repeaters

automatically re-transmit your signal over a much wider area, providing greatly

increased range. The Duplex mode only works on designated repeater channels 1 – 8

and 41 – 48. With Duplex selected on one of these channels, your radio actually

transmits 30 channels higher than it receives.

e.g. If Duplex is selected on channel 1, your radio will receive on channel 1 but will

transmit on channel 31.

Duplex can be enabled or disabled on individual channels. When Duplex is enabled on

the selected channel,

is displayed.

The Duplex mode is set through the Menu. Please refer to the Menu options further below.
